Theoretical study of multiple ionization of diatomic molecules by ion impact
Autor: Roberto D. Rivarola, C A Tachino, M E Galassi
Publikováno v: Journal of Physics: Conference Series. 58:271-274
In the present work we calculate multiple ionization cross sections, as a function of the orientation of the molecular axis with respect to the ion beam, for impact of highly charged ions on N2 and O2molecules. We use different approaches to obtain t
